Description

The flow passage structure of mould

Technical field

It the utility model is related to a kind of mould, more particularly to a kind of flow passage structure of mould.

Background technology

In the prior art, smallclothes die casting ranks multifarious, ununified ranking mode, as shown in Figure 1, being shown in figure Compare a kind of ranking structure 300 of routine, this ranking structure 300 is connect a plurality of runner by a sprue 301 302, every runner 302 connects a small pieces 200.Therefore, the die casting quantity of this ranking is 12, and die casting efficiency is not It is high；And runner 302 is excessive, more runner reclaimed materials is produced, improves production cost.In addition, independent die casting is each small Part small product size is small, and intensity is low, and the ejection balance of product is also bad, and ejection is easily deformed, and existing ranking can make mould Interior temperature is unstable, product thickness poor dimensional stability, and therefore, the product effect that die casting comes out is poor.

Utility model content

Improve that die casting efficiency, die casting effect be good, ejection is unlikely to deform, and has the purpose of this utility model is to provide one kind Effect reduces runner reclaimed materials, reduces the flow passage structure of the mould of cost.

To achieve these goals, the flow passage structure of mould provided by the utility model includes the first sprue, the second master Runner, multiple runners and big die cavity；One end of first sprue is connected with sprue, the other end and second mainstream Road connects；Second sprue is connected with the runner respectively, is laterally equipped with least two in the big die cavity in series Arrangement, it is each it is described arrange the small die cavity for being disposed in series at least two shaped articles, phase between the two neighboring small die cavity It is intercommunicated；The runner by cast gate correspondingly with the arrangement connection.

Compared with prior art, the utility model is in the big die cavity by being disposed in series at least two arrangements, then Be disposed in series the small die cavitys of at least two shaped articles in each described arrange, recycle the runner correspondingly with The arrangement connection, can be such that a runner is fed into the molding small die cavity of multiple needs, so as to reduce the number of runner Amount, effectively reduces runner reclaimed materials, reduces production cost；In addition, multiple products are molded in same big die cavity, can into Each product is linked to be an entirety after type, and then overall intensity is higher than the intensity of single product, put down the ejection of product Weighing apparatus property is good, and ejection is unlikely to deform, temperature stabilization in mould, product thickness dimensionally stable, and therefore, the product effect that die casting comes out is very It is good.

It is preferred that the flow direction of first sprue and second sprue is in be mutually perpendicular to, first sprue The other end be connected to the middle part of second sprue.

It is preferred that length direction of the orientation of each small die cavity in the arrangement along the small die cavity.

Specifically, the orientation of each small die cavity in the arrangement is identical with the material feeding direction of the cast gate.

Brief description of the drawings

Fig. 1 is the flow passage structure schematic diagram of the mould of the prior art.

Fig. 2 is the flow passage structure schematic diagram of the mould of the utility model.

Embodiment

To describe the technology contents of the utility model, construction feature, the effect realized in detail, below in conjunction with embodiment And attached drawing is coordinated to be explained in detail.

As shown in Fig. 2, the flow passage structure of the utility model mould includes the first sprue 1, the second sprue 2, Duo Gefen Runner 3 and big die cavity 4；One end of first sprue 1 is connected with sprue 5, and the other end connects with second sprue 2 It is logical；Second sprue 2 is connected with the runner 3 respectively, and laterally at least two rows are equipped with series in the big die cavity 4 Row 41, each arrangement 41 is disposed in series the small die cavity 42 of at least two shaping small pieces 200, two neighboring described small It is interconnected between die cavity 42；Specifically, it is interconnected between the adjacent small die cavity 42 in the same arrangement 41, It is interconnected between the small die cavity 42 corresponded in two adjacent arrangements 41.The runner 3 passes through cast gate Connected correspondingly with the arrangement 41.

The flow direction of first sprue 1 and second sprue 2 in being mutually perpendicular to, first sprue 1 it is another One end is connected to the middle part of second sprue 2.

Length direction of the orientation of each small die cavity 42 in the arrangement 41 along the small die cavity 42.And institute The orientation for stating each small die cavity 42 in arrangement 41 is identical with the material feeding direction of the cast gate.

Compared with prior art, the utility model is in the big die cavity 4 by being disposed in series at least two arrangements 41, The small die cavity 42 of at least two shaping small pieces 200 is disposed in series in each arrangement 41 again, recycles the shunting Road 3 is connected with the arrangement 41 correspondingly, and a runner 3 can be made to be supplied into the molding small die cavity 42 of multiple needs Material, so as to reduce the quantity of runner 3, effectively reduces runner reclaimed materials, reduces production cost；In addition, multiple products are same Shaping, can make each product be linked to be an entirety after shaping, and then overall intensity is higher than single production in a big die cavity 4 The intensity of product, makes that the ejection balance of product is good, and ejection is unlikely to deform, temperature stabilization in mould, product thickness dimensionally stable, because This, the product effect that die casting comes out is very good.

Above disclosed is only the preferred embodiments of the utility model, cannot limit the utility model with this certainly Interest field, therefore equivalent variations made according to present utility model application the scope of the claims still fall within the utility model and are covered Scope.
